Problems solved by technology

[0005] The technical problem to be solved by the present invention is that since the LED display module is pre-fixed on a metal box or metal frame, it is difficult to install and cause inconvenience to moving and transportation; and, when the boxes or frames are combined with each other , the connection through holes are generally set larger, so that the errors in the front, rear, up and down directions between the connected cabinets or frames are large, the flatness of the display surface between the cabinets or between the frames is low, and the display effect is poor

Embodiment 1

[0024] like figure 1 As shown, this embodiment provides an installation device for an LED display screen. The installation device includes a plastic frame 101 and one or more rigid support structures 103; A connecting unit 104, the first connecting unit 104 is used for fixedly connecting with the first connecting unit of other plastic frames; The connecting unit 102 is used for fixedly connecting with the second connecting unit of other rigid supporting structures.

[0025] The plastic frame 101 is injection molded from glass fiber polycarbonate plastic material. Polycarbonate is an engineering plastic with excellent performance. The mechanical properties and rigidity of polycarbonate can be improved by glass fiber reinforced polycarbonate, and the coefficient of linear expansion is greatly increased. Reduced, the dimensional stability is greatly improved, the molding shrinkage rate is significantly reduced, and at the same time, the defects of polycarbonate not resistant to ...

Embodiment 2

[0034] like figure 2 As shown, on the basis of the above examples, the first connection unit 104 is configured as a pinned connection piece, and the pinned connection piece is adapted to the pinned connection positions set by other first connection units, for example, In this embodiment, one side of the plastic frame 101 is provided with a pinned connector, and the plastic frame connected with the plastic frame 101 is provided with a corresponding pinned connection position, and the two plastic frames pass through the matched pins. The connecting piece and the pinned connection position are fixedly pinned to each other.

[0035] In order to further maintain the stability of the two plastic frames when they are connected to each other, the installation errors of the two plastic frames in the front and rear and up and down directions are small, the installation accuracy of the LED screen body is high, and the display surface after the LED display screen is installed has high flat...

Embodiment 3

[0038] like image 3 As shown, on the basis of the above examples, the rigid support structure includes two or more rigid support bars, for example, including a rigid support bar 103a and a rigid support bar 103b, two rigid support bars, a rigid support bar 103a and a rigid support bar The strips 103b play a role in bearing, fixing and maintaining the shape of the plastic frame 101 .

[0039] Moreover, the rigid support bars 103a and the rigid support bars 103b are arranged in parallel, and the arrangement of the support bars arranged in parallel is simple and beautiful; in addition, the rigid support bars can also be arranged crosswise.

[0040] In addition, the rigid support bars 103a and the rigid support bars 103b have a balanced mass relative to the plastic frame 101, that is, the rigid support bars 103a and the rigid support bars 103b are evenly arranged in the middle of the plastic frame 101, and at least the same as the plastic frame. The two sides of the 101 are fixe...

Abstract

The invention discloses a mounting device for an LED display screen as well as an LED display screen. The mounting device comprises a plastic frame and at least one rigid supporting structure, wherein at least one side of the plastic frame is provided with at least one first connecting unit for being fixedly connected with first connecting units of other plastic frames; the rigid supporting structure is at least fixed with two lateral edges of the plastic frame, and provided with a second connecting unit for being connected with second connecting units of other rigid supporting structures. The mounting device ensures that the LED display screen is flexibly mounted, the assembly accuracy of the LED display screen is high, the flatness of a display surface of the LED display screen is high, and the LED display screen is more convenient to move or transport.

Description

technical field [0001] The invention relates to an LED lighting device, in particular, to an LED display screen body mounting device and an LED display screen using the LED display screen mounting device. Background technique [0002] In the prior art, LED display screens are generally composed of several LED display modules, which can be used to display graphics, text, letters and animations, etc. Because LED display screens are generally susceptible to external influences, such as natural wind, vibration, collision, etc. Therefore, in the prior art, each LED display module is pre-fixed on a metal box or metal frame, and then a plurality of boxes or frames form an LED display screen. Each box or frame can play a role in each LED display module. It has the functions of fixing and protection, and can be used to install various LED display modules. The box or frame is generally made of metal, which is relatively bulky, making the installation more difficult, and at the same ti...
